Coilmaster Electronics (Established in 1995) - The Professional manufacturer for various kinds of passive component, such as SMD type of inductor(SMD Power Inductors / High current inductor) also known as Surface Mount Inductor / Power Inductor / High current power inductor, Through hole inductor (Radial leaded inductor), Common mode choke, Transformer, LAN magnetics. We also consistently improving quality of products and aims to offer various choices to customers. Provides various types of power inductor, magnetic and inductive to our customers with the best service and value is our vision.

Coilmaster Electronics have complete production line and adequate design experience in field of power inductors which could use to design in power supply inductor, SMD high current inductors, high saturate current inductor, high power indctor, surface mount inductor, or other circuit which may require a power inductor. Coilmaster’s sales person will provide the most suitable alternative inductor to you according to the request inductance value , DCR , IDC on the power inductor (custom inductors is also available for us).

If you already use other power inductor from different brand but with higher price, longer lead time. Coilmaster could provide the better solution to you. We could provide 100% alternative power inductors with same lay out and even with better characteristic. The free of charge samples is also available.

Common Mode Choke

SMD / THT Common Mode Choke

Coilmaster produces different kinds of common mode choke(Common mode inductor). Common mode choke could categorized by size, inductance, impedance, IDC, DCR…etc. Most common sizes for rated voltage are 50 V, 250 V and 500 V. We also carry common mode chokes with rated voltage as high as 250 kV. Rated current can be between 0.4 mA and 23 A, with the most frequent common mode chokes having a rated current of 500 mA, 1A or 2 A. Custom common mode inductors (common mode choke) is also available for us.

Common mode choke also could use to design on different applications, such as, high current common mode choke, Ethernet common mode choke, SMD common mode choke, surface mount common mode choke and for other applications which will use common mode choke, common mode inductor, common mode filter. If you need the alternative for other brand, please feel free to contact our sales people, we will provide the most suitable common mode choke product to you.

Transformer

High Frequency Transformer (SMD / THT type)

A transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction. A varying current in the transformer's primary winding creates a varying magnetic flux in the core and a varying magnetic field impinging on the secondary winding. This varying magnetic field at the secondary induces a varying electromotive (emf) or voltage in the secondary winding.

Coilmaster Electronics could offer the whole solution for customer who is looking for reliable quality of transformer. We could produce different kind of transformer, such as high frequency transformer, high power transformer, high voltage transformer, customize transformer and standard transformers. Both vertical transformer and horizontal transformer is available.

New product - Shielded High Current Power Inductor (Flat Wire) - SEP50XX series. As a professional manufacturer of Power Inductor, we will keep developing the new product which more than customer's expectations.
